WASHING MACHINE.

I Application filed September- 24, 1928. Serial No. 664,637.

To all whom it may concern:

Be it known that I, VVIL'roN S. SCHUYLER, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in NVashing Machines, of which the following is a specification.

This invention relates to washing machines, it more particularly relating to means for partly counter-balancing the agi- The object of my invention is to provide a simple and effectivemechanism for partly counter-balancing the agitating device of a washing machinevwhether it be an oscillatory cylinder, an oscillatory dolly, an oscilla-' tory semicylindrical scrubber or other form of agitating device so that the device may be readily removed from the tub or casing in which it operates.

A further and more specificobject of the invention 'is to provide a mechanism of the character referred'to consisting of'a sprin member or member'sv arranged to be place under increasing tension as the agitating device is lowered into the tub so that in removing the device from the tub the springs will act to assist in raising the same.

In the accompanyingdrawings:

Fig. 1 is a top plan view of a washing machine of the oscillatory cylinder type with the cover removed showing my improved mechanism applied thereto.

Fig. 2 is a vertical section of the machine with the cover shown in position thereon, the section being on the line 22 of Fig. 1.

Fig. 3 is a top planpartly in section on an enlarged scale of a portion of the machine and counter-balancing devices.

Fig. 4 is a side view of one of the supporting arms for the agitating member with the shafts in section.

Fig. 5. is a section on the line 5- -5 of Fig. 3.

In the drawings the improvements have been shown applied to a washing machine of the oscillatory cylinder type.

The tub proper is indicated at 1, being preferably formed of sheet metal which isthe frame 2. The top of supported upon the tub is enclosed in theusual way by a lid- 3 and there is mounted in the tub a cylinder 4 which has means (not shown) for oscillating the same. The shaft 5 of the cylinder is mounted in open-top bearings 6 ser 1,514,469 PATENT OFFICE.

cured to the casing so as to permit the cyl-i inder to be removed from the tub when desired. A rock shaft 7 extends transversely across'one end of the tub near the upper portion thereof, this rock-'shaftbeing mounted in bearings'8 which are secured in the ends threaded to receivenuts 12 so that the tube may firmly clamp against spacin which are placed between the tu e and the 'inner wall of the casing. g A pair of arms 14 are secured to'the' rock blocks 13 v shaft 7 by set screws 15 and the free ends of;these' arms are secured to lugs 16 projecting from sleeves 17 loosely mounted upon the cylinder shaft 5 at each end of the cylinder.

One end of the shaft 7 projects through the'casing 1 and is provided with acrank handle 18, a detent in the nature: of I a pin 19 arranged to engage either one of' a pair' of recessed members20-secured tothe tub 1 so as to hold the the cylinderin either raised or lowered position; a spring 21-being preferably employed to'press the pin to engaging position. But one of these recessed members is shown in the present case, spects like the one shown and located at the other limit of movement of the crank handle 18. To partly counter-balance the weight of the cylinder 4 there are employed a pair of coil springs 22, one at each end of the rock shaft 7'. The inner end of each of these springs is inserted in an aperture in the lug 23 projecting from the bearing 8 while the other end of the spring is bent and projects beneath its corresponding arm 14 as clearly shown in Fig. 3.

Asa resultof this construction, when the cylinder is lowered into the casing, these springs are placed under increasing tension, the maximum tension being such as to nearly but not quite counterbalance the weight the other member 20 being in all reof said agitating member, and arranged to partly counterbalance the weight of said member.

2. In a washing machine, a tub, arock shaft supportedfrom the inner face of one of the :Walls of said tub, a pair-"of armsprojecting from said rock shaft, .an agitating member carried by the free ends ofsaid arms, and a pair of coil springs about said I rock shaft, one end of each spring being secured to a stationary part and the other end thereof bearing upon one of said arms.

3. In a washing machine, a tub, a rock shaft supported from the inner face of one of the Walls of said tub, arms connected to said rock shaft, .an agitating member supported by the free ends of said arms, a pair of coil springs about said rock shaft and cooperating with said arms to partly counterbalance the weight of said agitating member, said rock shaft being extended through a Wall of said tub, and a crank arm on the outer' end of the extended part of said shaft for raising andlowering said agitating member.

4., In awashing machine, a tub, a rock shaft supported from the inner face of one of the walls of said tub, arms connected to said rock shaft, an agitating member supported by the free ends of said arms, a pair of coil springs about said rock shaft and cooperating with said arms to partly counterbalance the weight of said agitating member, said rock shaft being extended through aWall of said tub, and a crank arm on the outer end of the extended part of said shaft for raising and lowering said agitating member, and a detent carried by said crank arm to hold the same in different positions of adjustment.

5. In a washing machine, a tub, an oscillatory member, a rock shaft supported by a said tub having one end projected through said tub and provided with a crank arm,

arms connecting said rock shaft with said member, a pair of coil springsabout said rock shaft, one end of each spring having a connection with its correspon ing arm and the other end of said spring being connected to a stationary point, whereby when said will be placed. under increasing tension.

6. In a washing machine, a tub, an oscillatory member, a tubular member connected with said tub having a bearing at each end thereof, a rock shaft journaled in said bearings, arms connected withsaid rock shaft and also with said oscillatory member, and

.a pair of coil springs at each end of said tubular member, one end of each spring' having a connection with its corresponding arm and the other end thereof belng con nected with the corresponding bearing,

whereby when said oscillatory member 1s lowered said springs will be placed under increasing tension. e I

In testimony whereof, I have hereunto set my hand this 21st day of September, 1923.
